I am not even comparing this to the Greasy Strangler as a movie, just referring to the title ... if anything they are both quite trashy as some would say, but in a different sense. This is quite episodic and I reckon some people who did do drugs, may feel some connection to some of the things happening here. Still it has to be noted, you should not try this at home. And even someone like me, who didn't do drugs (alcohol aside if you think it counts per definition), I could relate ... well understand may be the better word, what the main character goes through, to a degree.
Very well played by our lead and far out as some might say. But also completely odd and tough to follow. Also no story - just a few things to be aware of. This isn't anywhere near a "normal" film ... but if you let yourself into the world and the madness this depicts ... you can have some fun, with all the depravities you get to see. Or be entertained by them I should say ... fun isn't really ... well I guess you can laugh a lot, especially if you can distinguish and not compare this to your real life (hopefully) ... no pun intended
